Provided for is a radio frequency identification (RFID) chip to be connected to a printed circuit board (PCB). The RFID chip includes an RFID antenna for receiving a radio wave from an RFID controller. The RFID chip also includes a register driven by induction power generated by the radio wave received by the antenna. The RFID chip writes data indicated by a write request from the RFID controller into the register being driven by the induction power, without power being supplied to the PCB from a host device containing the PCB.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A radio frequency identification (RFID) chip to be connected to a printed circuit board (PCB), the RFID chip comprising: an RFID antenna for receiving a radio wave from an RFID controller; and a register driven by induction power generated by the radio wave received by the RFID antenna, wherein the RFID chip is configured to write data indicated by a write request from the RFID controller into the register being driven by the induction power, without power being supplied to the PCB from a host device containing the PCB; and wherein the RFID chip is configured to write data indicated by the write request from the RFID controller into the register asynchronously during runtime of the PCB.
2. The RFID chip of claim 1 , wherein the data comprises an initial setting value for the PCB.
3. The RFID chip of claim 1 , further comprising a comparison circuit driven by the induction power, configured to compare one or more first values received from the RFID controller with one or more second values stored in the register.
4. The RFID chip of claim 3 , wherein the comparison circuit is configured to compare a first security key received from the RFID controller with a second security key stored in the register, and wherein the RFID chip writes the data into the register upon determining the first security key matches the second security key.
5. The RFID chip of claim 3 , wherein the comparison circuit is configured to compare a first card identification value received from the RFID controller with a second card identification value stored in the register, and wherein the RFID chip writes the data into the register upon determining the first card identification value matches the second card identification value.
6. The RFID chip of claim 1 , further comprising a status circuit driven by the induction power, wherein, when the RFID antenna receives a status request from the RFID controller, the status circuit transmits status information about the PCB to the RFID controller via the RFID antenna.
7. A method for interacting with one or more printed circuit boards (PCB) using radio frequency identification (RFID), the method comprising: identifying one or more PCBs each connected to one or more RFID chips; sending first radio waves to the one or more RFID chips, wherein the first radio waves include settings for the one or more PCBs; sending second radio waves to the one or more RFID chips, wherein the second radio waves include a request for status information from the one or more PCBs; and receiving status information from the one or more RFID chips; wherein the status information includes a plurality of voltage values corresponding to voltages present on the one or more PCBs.
8. The method of claim 7 , wherein the sending the first radio waves occurs when the one or more PCBs are not connected to a power source.
9. The method of claim 7 , wherein settings for the one or more PCBs are initial setting values for a first use of the one or more PCBs.
10. The method of claim 7 , wherein the first radio waves include one or more first values for comparison with one or more second values stored in the one or more RFID chips.
11. The method of claim 10 , wherein the one or more first values includes a security key.
12. The method of claim 7 , wherein the one or more first values includes a card identification value.
13. A system for interacting with one or more printed circuit boards (PCB) using radio frequency identification (RFID), the system comprising: one or more PCBs each connected to one or more RFID chips, wherein the one or more RFID chips are grouped together and positioned separately from the one or more PCBs; and an RFID controller device comprising: one or more processors; and a memory communicatively coupled to the one or more processors, wherein the memory comprises instructions which, when executed by the one or more processors, cause the one or more processors to perform a method comprising: sending first radio waves to the one or more RFID chips, wherein the first radio waves include settings for the one or more PCBs; sending second radio waves to the one or more RFID chips, wherein the second radio waves include a request for status information from the one or more PCBs; and receiving status information from the one or more RFID chips.
14. The system of claim 13 , wherein the sending the first radio waves occurs when the one or more PCBs are not connected to a power source.
15. The system of claim 13 , wherein settings for the one or more PCBs are initial setting values for a first use of the one or more PCBs.
16. The system of claim 13 wherein the first radio waves include one or more first values for comparison with one or more second values stored in the one or more RFID chips.
17. The system of claim 16 , wherein the one or more first values includes a security key.
18. The system of claim 13 , wherein the status information includes a plurality of voltage values corresponding to voltages present on the one or more PCBs.
